The invention relates to the technical field of
energy storage batteries, and provides an immersed liquid
cooling energy storage PACK box. The battery compartment is placed by arranging the outer frame, so that the stability of the battery compartment is ensured; the main box body of the battery cabin is formed by bending, so that the forming difficulty of a single
stamping part is reduced, and the integral sealing performance is improved by performing aluminum
brazing connection on the main box body and the corner fittings; according to the liquid cooling plate, efficient
heat management and low-flow-resistance operation are achieved through three-inlet and one-outlet flow channel
layout and
optimal combination of confluence of three parallel
inlet flow channels and one outlet flow channel; the battery cells of the battery module are completely immersed in the insulating cooling liquid, and the insulating cooling liquid adopts
mineral oil or fluorinated liquid, so that through the composite cooling design of heat dissipation of the static immersion liquid and the bottom liquid cooling plate, the problem of
liquid circulation existing in traditional immersion type cooling is effectively solved, the auxiliary heat conduction function of the immersed insulating cooling liquid is fully exerted, and the service life of the battery module is prolonged. And in cooperation with the liquid cooling plate, the
system temperature difference is successfully controlled at an excellent level of 3 DEG C, and the overall heat dissipation efficiency is remarkably improved.
